Definition Health

NHS problem

All surgical patients must undergo a pre-assessment to ensure suitability for the procedure and inform them of the health benefits and risks of undergoing it. Legacy processes are inefficient as they are both labour and paper intensive and often result in unnecessary patient attendances (pre and post surgical). Twelve million people undergo procedures each year with an estimated cost of between £54 – £74 per pre-assessment and further costs relating to short notice cancellations, litigation and readmissions which are largely avoidable.

The solution

Founded by hospital doctors, software engineers and business managers, Definition Health uniquely delivers a personalised, digital approach to surgery for patients and hospitals; offering maximum flexibility in the way hospitals communicate with, perform pre-assessment on, and rehabilitate patients, wherever they may be. Definition Health drives clinical excellence into pre-assessment and post-discharge pathways, through a personalised but standardised approach in collecting critical health information from the patient, increasing hospital efficiencies and clinical outcomes.


Definition Health has the capacity to save the NHS over £500m if cost savings are repeated.

  • In Definition Health’s first hospital contract, which lasted three years, it made cost savings of over £94,000 per 5,000 patients through a 60% reduction in outpatient face to face appointments, delivering a return on investment in under 6 months
  • Definition Health now works with many NHS Trusts across the UK, all of which report material operational efficiencies having been delivered in line with expectations
  • Definition Health’s solutions support waiting list triage, assisting NHS Trusts to rapidly recover post Covid-19
